#InterSystems IRIS

Hi all,

I'm exited to announce a GitHub Action to do direct deploy code from a github repository direct to a IRIS Instance.

Pleas visit https://openexchange.intersystems.com/package/Github-Action-IRIS-Deployer

I have a widget that uses "choose Data source" control option. Termlist for the control consist of the two data sources and i want to set one of them by default. For example: I have two data sources, one is grouped by month, the other by year. I need to set the one that is grouped by year by default 

Using default value at the bottom return an error

How can i achive that?

Hello,

We had a weird behavior of task manager in mirror async backup-failover pair:

1. server 1 was primary, server 2 backup for over a month, as there was no automatic failover (switch) both had IRIS up for over a month
2. We manually switched making server 2 primary
3. The tasks that had this issue were set to "run on Primary only"
4.Task manager started to execute tasks every minute: we noticed that "Next scheduled time" is always calculated in past date, and progressing by the task interval (e.g.a task that supposed to run every hour will have "Next scheduled time" in the past e.g.

I have a rest API Class used for getting data from Cache 2018 version.
I have single route '/callfuntions'
I send the following parameters to the API :-  className, methodName, params
I use $CLASSMETHODto execute and send the result back to the client.

If I make more that 10 to 12 requests in quick succession, then it stops sending data.

if I wait for over 10 seconds it allows me to send more requests to the API.  How do I resolve this?

I am writing to express my interest in the "IRIS Ensemble Integration . I have 2 years of experience as an Ensemble IRIS Developer, working with Ensemble and IRIS for integration, server management, and application development. Looking for more opportunites to work under Iris Cache Objectscript

Hi community,

The aim of this article is to explain how to create messaging between IRIS and Microsoft Teams.

In my company, we wanted to monitor error messages, and we used the Ens.Alert class to redirect those error messages through a Business Operation that sent an email.
The problem was that we sent those error messages to a support account where there were many emails. We wanted something specific for a specific team.

So we investigated how to make these messages reach the development team directly and they could have, in real time, a notification of an error in our production.
In our company we use Microsoft Teams as a corporate tool, so we asked ourselves: How could we make these messages reach the IRIS development team?

If anyone has a custom checklist of tasks that must absolutely be done when doing this upgrade to make sure everything is included and nothing is lost or destroyed, we would greatly appreciate it? We have the generic checklist provided on the support websites but we run custom build classes, ftp, tcp-ip, batch, etc.

Thanks,

Jonathan Harris

For background, I've developed code that relies on %JSON.Adaptor functionality across an entire package of classes in our codebase. In regenerating these classes with %JSON.Adaptor as a superclass, I've encountered compilation errors from the JSON adaptor generators in certain classes, triggered by certain property types or parameters that are incompatible.

There are two causes for these compilation errors: either 1) the property is computed, and therefore certain property methods in the code generated by the JSON adaptor, such as ..SetObjectId(), do not exist, or 2) the property is an array

Hello Community,

Is it possible to retrieve/find all the names of subroutines, procedures, or functions from a deployed routine?. in the routine below, how can I extract names like x2 and execsql? I’ve just tried using openId on %RoutineMgr  but it didn’t help.

xdeploy.mac
xdeploy
 quit
x2 ; test1write123q
execsql(sql) ; test2Set tResult = ##Class(%SQL.Statement).%ExecDirect(,sql)
 Return tResult

Thanks

Developing with InterSystems Objects and SQL – In PersonJune 9-13, 2025

• This 5-day course teaches programmers how to use the tools and techniques within the InterSystems® development environment.
• Students develop a database application using object-oriented design, building different types of IRIS classes.
  
  • They learn how to store and retrieve data using Objects or SQL, and decide which approach is best for different use cases.
  • They write code using ObjectScript, Python, and SQL, with most exercises offering the choice between ObjectScript and Python, and some exercises requiring a

I'm playing with %Net.DB.Iris and stumbled over a mystery

set con=##class(%Net.DB.DataSource).CreateConnection(host,...)
set srv=con.CreateIris()
write srv.ClassMethodValue("%SYSTEM.Util","InstallDirectory")

Entering the above lines (in a terminal session) on my local instance yields the correct answer for:

host = "localhost"
host = the real IP of localhost (i.e. host="192.168...")
host = "10.x.y.dev" customers development system (over a VPN tunnel)

but for

We are attempting to send HL7 messages over to CBOARD NetMenu over HTTP using SSL. We set this up using the EnsLib.HL7.Operation.HTTPOperation adapter. When we attempt to send the message we are receiving 

MSH|^~\&|||DIETOE|A6M0|202505131437||ACK^HTTP^415|00|P|2.1 MSA|AE|9165602|HTTP (N)ACK 'HTTP/1.1 415 Unsupported Media Type'

The vendor mentioned something about putting a SOAP/XML wrapper around the HL7 message but isn't that what the HTTPOperation adapter does? Why would we be getting Unsupported Media Type. How would we go about setting the Media Type for the HTTP HL7 message?

Hello everyone,

I am attempting to implement continuous integration using Docker with Caché 2018.1, and I am in the process of creating an image for our client. I have already installed Caché 2018.1 on the RedHat server, but I am working on a script to create the database and namespace. For the database, I used the following code:

do ##class(SYS.Database).CreateDatabase("/usr/cachepoc/cache2018/mgr/poc/")

However, I have encountered some issues with this code. For instance, I am unable to view this local database in the portal's list:

In the end, I have tried various approaches to create the

Hello Community,

I executed the below query in the %ZLANGC00.mac routine. It returns results when using dynamic SQL, but not with embedded SQL(returns 0). 

 &SQL(SELECTcount(*) INTO :Cnt FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'")
 Write "SQLTablecount : "_Cnt,!
 Set tResultSet = ##class(%SQL.Statement).%ExecDirect(,"SELECTcount(*) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'")
 Do tResultSet.%Display()

Thanks!

Hello,

I have a problem with the deployment. When I deploy using the Ens.Deployment.Deploy class, I no longer receive the logs in the terminal. However, the deployment went well, I see it in the history on the portal.

It works on our environment, but not on the client's.

Set tSC = ##class(Ens.Deployment.Deploy).DeployCode(chemin_"GESL_SVCCLI_DEPLOY_CPT-243_V4_0.xml","SVCCLI.ProdClient",1,chemin_"GESL_SVCCLI_DEPLOY_CPT-243_V4_0_rb.xml","L",chemin_"GESL_SVCCLI_DEPLOY_CPT-243_V4_0.log",1,1)

Thank you 🙂

According to documentation, quotation: "$THIS contains the current class context.
The class context for an instance method is the current object reference (OREF).
The class context for a class method is the current classname as a string value."
 
As my example below shows, either the documentation or the implementation (or both) is wrong, I always call a class method (Value) and expected the class name as the return value but got either the class name or an OREF. Moreover, if I repeat the call, I get another values. But why?
Does anyone have a clear explanation (for an aging brain) or have I

I use the following code to protect some code for being called by multiple processes at same time :

lock +^TEMP("FOO"):0//don't waitquit:'$test//critical section//...lock -^TEMP("FOO")

This works between processes but it does not prevent the same process entering critical section twice.

How to do that, is there any lock option ? I would like it to behave as the lock in C# or Java.

It's OK for me to use something else than LOCK instruction (eg : signals)

There are a lot of great community articles regarding "vector search on IRIS", and samples in OpenExchange. Everytime I see these, I'm so excited to know that so many developers already try vectors on IRIS!

But if you've not tried "Vector Search on IRIS" yet, please give me one minute 😄 I create one IRIS class - and with only one IRIS class you can see how you put vector data in your IRIS database and how you compare these in your application.

If you are a customer of the new InterSystems IRIS® Cloud SQL and InterSystems IRIS® Cloud IntegratedML® cloud offerings and want access to the metrics of your deployments and send them to your own Observability platform, here is a quick and dirty way to get it done by sending the metrics to Google Cloud Platform Monitoring (formerly StackDriver).

I am running into an issue where a JSON response is missing keys...

{
    "count": 0,
    "pageInformation": {
        "offset": 0,
        "size": 10
    },
    "items": []
}

Within the JSON response I am only looking for two fields portalUrl and portalId. I have tried using $LENGTH and %IsDefined to check if they are valued but neither work. 

  If ((tHttpResponseIsObject) && ($ZCONVERT(tHttpResponseContentType,"L") [ "application/json"))

Hi Community,

Regardless of whether an instance of IRIS is in the cloud or not, high availability and disaster recovery are always important considerations.While IKO already allows for the use of NodeSelectors to enforce the scheduling of IRISCluster nodes across multiple zones, multi-region k8s clusters are generally not recommended or even supported in the major CSP's managed Kubernetes solutions.However, when discussing HA and DR for IRIS, we may want to have an async member in a completely separate region, or even in a different cloud provider altogether.

Hello Community,

When retrieving strings from the DAO, if the string exceeds the capacity of an ObjectScript string variable, it returns <MAXSTRING>. To prevent this, use dao.%Get(key, default, "stream") to retrieve the value as a stream (%Stream.DynamicBinary). However, Why can't we use other stream objects such as %Stream.TmpCharacter instead of %Stream.DynamicBinary/%Stream.DynamicCharacter (I understand It is not possible to create a direct object instance for %Stream.Dynamic* classes) .Since both streams are not stored in the database, is there a specific reason for using one over the

Ideally I would like to use a variable instead of repeating the Piece repeatedly throughout the rules.

When AMD published the x86-64 standard in 1999, little did they know they were inventing what would become the de-facto architecture for server CPUs.  But the CPUs of today aren’t the same as ones produced 20 years back – as they have extensions for everything from Advanced Vector Extensions (AVX) to Hardware-Assisted Virtualization (VT-d).

InterSystems would like to take better advantage of these new extensions in upcoming versions of InterSystems IRIS.  While our compilers are smart enough to create optimized code for many situations, some optimizations can only be turned on by explicitly cutting off support for processors that do not have that instruction set. Additionally, we are finding it increasingly difficult to maintain older CPU models to test on.
